Blackscreen and fan's 100%

Hello,

I'll give the full story of whats happening.

So basically, about 5 days ago while playing Far Cry 3 my computer randomly turned off and wouldn't turn back on. At first I thought the outlet died, but when I changed to another station, it still wouldn't turn on. So I began unplugging parts seeing if anything was faulty. The first thing I unplugged was the GPU and the system booted fine. With the actual card still plugged in, but not pluged into the PSU everything worked fine so I guessed it was the GPU, so I bought a 670 off newegg and got it today.

Everything was going fine, it booted fine and everything. I installed the drivers and everything seemed fine. No errors in the devices list or anything. Everything was detecting the 670 perfectly.

I loaded up World of Warcraft and began talking to couple of friends, about 1 minute of being loaded into the game, my screen suddenly went black and the GPU fans were at 100% speed, producing one hell of a noise. When I looked inside, the CPU fan was still going as well as the HDD and Drivers aswell as the other fans.

I thought the old drivers were still installed and were fucking with my system, so I removed all drivers and got the drivers from the install disk... No luck, it still crashed whenever I launched a game, be it Far Cry 3 or World of Warcraft.

You were pretty much wrong there. The PSU is the problem, not your GPU. If the PC doesn't turn on, it's the psu or just a dead motherboard but in this case, your PSU is heavily doomed. Could you say us which gtx 670 you actually use? Sometimes some situations happen that a card is causing game crashes because the factory overclock wasn't stable. When you unplug the card from the PSU but still connected on the motherboard, the GPU is getting still power from the motherboard which could be using another voltage rail which can still be stable, while the gpu's rail is being f***..

To explain it easier, a PC doesn't need a graphics card to boot up to windows

If you had nvidia drivers, uninstall the drivers, run driverfusion (the link I just gave), perform clean installation (select advanced mode in nvidia setup).

Possibly you can try to run furmark, select 1080p and check if the gpu usage is at 99%, if it's not, your psu is doomed which is another proof.

After posting, I tried my backup PSU and it had the exact same issue; crashing whenever a game loads up. So unless somehow both of my PSU are broken, I think it's a driver issue. I've reinstalled Windows fresh.

Is it this errorcode? http://imgur.com/S3llm - But my pc complety froze, but I'm encountering issues now too. Might be my overclock isn't stable but I have to test it out and I've been lazy.

If you have a friend which wants to help you out, get both of your power supplies & graphics card and test the first time with his power supply and your graphics card if it's running fine, try your power supplies and if it's running fine -> motherboard/ram.

So you say that you tried a "Back-Up" power supply. Was this supply one that you had to replace before, or from another computer? It could be that the power supply you currently have installed is dying, and the power supply that you tested it with didn't have enough juice.

Without more specifics we won't know. But the first few steps are ones that you seem to have completely jumped over. You re-installed windows, and still encountered the same problem. So now work to be sure every portion of your hardware is functioning correctly.

Start by removing your overclock. 3.8 Ghz isn't a large overclock by any stretch of the imagination but you don't know if that could be the issue. How stable was that overclock when you tested it after? Did you run prime95 for 12+ hours without fail?

When having computer problems with an overclocked computer clock everything down to recommended settings and see if you still have the problem. This means memory needs to be set at 1333 and processor at 3.4 Ghz.

If you still encounter the problem start by removing your RAM. If it is 4x2GB sticks remove 2 sticks at a time, if it is 2x4GB remove 1 stick at a time. If none of this remedies the problem you probably have a fault in your mobo which could mean a new mobo is in your future.

Just a shot in the dark, but im thinking the computer will fire up and work fine when your overclock is removed. I ran my 2600k at 5Ghz for just under a year until degradation made it unable to be overclocked at all. It was stable one day, and then completely unstable with any overclock the next day.

Just to clear out, such as dxdiag is not going to show your turbo ratio clock. People are overclocking with the turbo ratio. The 3.8GHz is his boostfrequency (intel turbocrap).

Setting memory to 1333MHz, not at all. Disabling intel turbo, no point.

Actually I just read he has a 2600k. I've been encountering this problem as well and I'd like to know the motherboard model as well. System Manufacturer: Gigabyte Technology Co., Ltd.
System Model: To be filled by O.E.M.

Btw, the reason why you're 2600k wasn't stable after a year is just because you exceeded the limit of 1.45Vcore.

Right let me start, this is kinda the best way to find if you encounter issues or trying to test the cpu/mb/ram

Prime95
Small fft's -> torturing the CPU & the cache
Large FFT's -> torturing ram, MB & IMC
Blend -> Between those two

Just to solve it, the first test shouldn't be any issue. A working cpu is a working cpu, halfworking cpu doesn't exist.

I'd say, start to lower your RAM speed as much as possible down and run the Large FFT's mode. If this fails, your motherboard is doomed. If this doesnt fail, PSU or RAM.

If you want to test the ram ONLY, set your memory settings back to stock, memtest86+

I've just been running prime95 small fft's to test my overclock and passed over 7hours and now doing large FFT's and it's still running after 8hours. So my problem is either the PSU or I just messed up with my drivers. My PSU seems to be making loads of strange noise and not able to give enough juice for my 2x gtx 680's. They're not reaching a gpu usage of 99% at all.

This just requires a lot of time, but the only choice which is being left is either the PSU's, motherboard or ram.

My guess is that the cables aren't properly seated in either the PSU or the GPU itself. When I first installed my new one, a cord came loose and the fans went full fucking blast until I narrowed it down to the cables

Yeah i completely forgot about turbo, so there really is no reason to disable it. The comment you made regarding memory and 1333 "not at all" makes no sense to me though. I didn't find memory timings in his dxdiag, at least I didn't look far enough to find them. If he is running memory at faster than 1333 he very well may not have volted it correctly or set the timings correctly. Setting it down to 1333 is just another step in narrowing down what is causing the problem.
